Design of integrated radio meteorological parameter monitoring system based on LoRa

The meteorological parameters can characterize the law of change and characteristics of radio waves. In order to study the impact of various meteorological changes on radio waves, it is necessary to accurately measure and remotely manage radio meteorological parameters, thus we propose the design and implementation of an integrated monitoring system for radio meteorological parameters based on LoRa. The specific design and implementation scheme are as follows: using LoRa as a wireless communication transceiver device, long-distance communication using Beidou short message technology, using low-power STM32 microprocessor at the meteorological monitoring node, which is transplanted with uCOS-Ⅲ real-time operating system to realize multi-task scheduling of multi-sensor integrated system, using Qt to design the matching host computer software for real-time processing, analysis and display of weather data at the remote terminal. The measured results show that the data transmission packet loss rate is less than 10%, and the host computer software can accurately display and store weather data when the communica- tion distance is less than 2 km. The system has the characteristics of stability, reliability, high integration, network convenient, and long communication distance. It can realize real-time collection and remote management of radio meteorological parameters in complex environments, which provides effective meteorological parameter data for radio meteorology research.
